I just stopped by my local Sherwin Williams and they sold me some of their top quality($40 a gallon regular price) paint for $5 a gallon.
They had some that was mis tinted. I got some light yellow for the interior of the coop.
Then they sold me some other good paint(regular price $20 or $25 a gallon) though not their best stuff that they wanted rid of for $5 a gallon I picked the color. So I matched the color of my house as best I could from memory. This is for the exterior and both paints were exterior grade.
I just built my coop and was already over my planned budget.
So this cheap paint helped the pocket book.
Just an option for you. Check your local paint store for a mis tinted paint or some other discounted paint.
Of course if you have the budget get what you want this just worked for me.
